Ablock is released from rest at the top of a plane inclined at an angle of 21◦ . the coefficient of kinetic friction varies along the plane according to the relation µk = σx, where x is the distance along the plane measured in meters from the top and where σ = 0.7 m−1 . the acceleration of gravity is 9.8 m/s 2 .

determine how far the block slides before coming to rest. (hint: find the acceleration of the block and integrate to find the velocity. note that dv dt = dv dx dx dt answer in units of m

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

it doesn't. it was imagined up in the middle ages.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
